The fatbike has taken off in recent years. Originally designed for sand and snow, these sturdy bikes with their thick tyres are now a fixture on Dutch streets. But their popularity, their speed and sometimes their questionable technical condition mean that both the number of accidents and the complexity of the liability questions are increasing.
Have you been involved in a fatbike accident, as a rider or as a victim? Then it matters how the law assesses your position and who is responsible for compensating your injury. This article sets out how a fatbike is classified in law, the difference between a vulnerable and a non-vulnerable road user, and the steps to take to secure your letselschade fatbike succesvol te claimen.
Classification: is a fatbike a bicycle or a moped?
Liability in fatbike accidents turns on the juridische classificatie of the vehicle. Does the fatbike fall under the protection given to vulnerable road users, or is it treated as a motor vehicle?
1. The fatbike as a vulnerable road user (standard e-bike)
A fatbike counts in law as an ordinary bicycle, provided it meets the requirements of the Road Traffic Act:
- Assistance cuts out at a maximum speed of 25 km/u.
- The electric motor output is no more than 250 Watt.
- You must keep pedalling in order to move.
If you meet these requirements you are a zwakke verkeersdeelnemer. If you are hit by a motor vehicle you have the strong protection of Article 185 of the Road Traffic Act, which produces the favourable 50%- en 100%-regels.
2. The fatbike as a non-vulnerable road user (tuned or faster)
Many fatbikes are tuned or go faster than 25 km/h. In law these are speed pedelecs of zelfs bromfietsen. On these faster models you are a sterke verkeersdeelnemer, with all the obligations that go with it (third-party insurance, helmet, driving licence).
In an accident with a motor vehicle the protective rules of Article 185 of the Road Traffic Act do not apply. Liability is then determined by the ordinary traffic rules, which makes claiming letselschade fatbike aanzienlijk complexer maakt.
Liability scenarios in fatbike accidents
Who is liable depends heavily on who was involved and on how the fatbike is classified:
Casus 1: Fatbike (Zwak) versus Motorvoertuig (Sterk)
The fatbike rider has the strong protection. The car driver is almost always liable under Article 185 of the Road Traffic Act. Even where the rider made traffic errors of their own, they are entitled to at least 50% of the compensation.
Casus 2: Fatbike (Sterk/Opgevoerd) versus Motorvoertuig
The fatbike rider is treated as a non-vulnerable road user. Liability rests with whoever made the traffic error, which makes the burden of proof heavier. Our personal injury lawyers help build the claim after a road accident so that your position is as strong as it can be.
Casus 3: Fatbike versus Voetganger of Gewone Fietser
Because the pedestrian or ordinary cyclist is the most vulnerable party, the fatbike rider will often be held liable, particularly where the fatbike is classified in law as a motor vehicle.
